Task wise revenue recognition

 Hi,

I am trying ti find out the solution for one Problem in Job Costing Module.

Revenue is recognition is based on % completion at Project Level, 

but the client requirement is in one project they have different task & for each task revenue is identified separately.

There will be task wise revenue account and task wise cost. At the time of update of % completion, system should allow to update the % completion

task wise not on project level & revenue recognition should be done accordingly & updated against revenue account for each task.

Client don't want  to create separate project for each task.

For Eg there are two task involved  Mechanical Work with the Price of $10000 & Electrical Work $ 20000
